Research group is focused on the development of lab-on-a-chip system with fundamental understanding of bio-molecular interactions and fluidic behavior in micro/nano scales. A family of unique microfluidic platforms are utilized to probe cells with unprecedented precision and to have systems understanding of cellular communications in tumor microenvironment. Current research topics include a lab-on-a-disc for the detection of rare cells, exosomes, and cancer biomarkers, quantitative analysis of single cells, and system analysis of cell to cell communication.
